pitch in thumb is huge. Ihave a long span and for years I was using @ 3/8" away pitch. Recently after never quite being relaxed in thumb grip I went in an 1/8th time till now my whole arsenal is drilled 0 in the thumbs and I have a couple IT thumb slugs drilled at the 0 and a couple drilled to fit the 0 balls but an 1/8th away drilled into the thumb slug. Mostly use the 1/8 away slugs but at 6'4" w a questionable back sometimes the 0'S work better.
